Filed: 2020-03-13
Abstract: To prevent unintended outflow of working fluid even if a pressure of working fluid rises in a pipe.SOLUTION: In an electromagnetic valve at the time of no energization, a normally-closed valve seat is closed by a valve element. Valve bodies are provided with an inflow passage for working fluid, an outflow passage for the working fluid, and a pressure relief passage that bypasses the normally-closed valve seat and connects the inflow passage and the outflow passage, and a pressure relief valve is disposed in the pressure relief passage. The pressure relief valve closes the pressure relief passage when a pressure of the working fluid in the outflow passage is lower than, equal to, and higher, by a pressure difference less than a predetermined relief pressure, than the pressure of the working fluid in the inflow passage. The pressure relief valve opens the pressure relief passage when the pressure of the working fluid in the outflow passage is higher, by a pressure difference equal to or higher than the relief pressure, than the pressure of the working fluid in the inflow passage. Therefore, by opening the pressure relief valve, it is possible to prevent the pressure of the working fluid in the outflow passage from becoming equal to or higher than the predetermined relief pressure.SELECTED DRAWING: Figure 2
